Oxygen

[helsekia]

I was wondering what the best way to add oxygen into the water is?I have a 61/2 foot tank with a spray bar from the filter and an air curtain coming from a seperate air pump.the fish are all fine but the sharks are quite big so want to aerate the water properly.has anyone got any suggestions?if so how do they work?should I take the air curtain out?Is it possible to over oxygenate the water?
thanks in advance

Lots and lots of surface turbulance

If you have an aircurtain along with a spray bar, you are already having plenty of oxygen in there.

yes I understand that you need to break the surface of the water but what I need to know is what will do that best


Nim I love your tank on the piccy by the way.do you think what i have is sufficient?
